Replying to Help on not flailing everywhere

I flail sooo bad and need help fixing it. Most my spins no matter how big the jump I always flail. Doing 3s, and 5s on the pro line at tremblant I always flail like fuck and everyone always thinks I die, but I somehow pull it together in the end and land everytime. My friend told me to just go with a really wide stance, and sometimes that helps, when I go super exageratly wide, but not always, im still flailing real bad. And whenever I try 7s I get super nervous and throw my spin way to hard and do a 5 thats even more flailed. Any ideas?
